Index
• Si vous modifiez le paramètre de couplage d’entrée alors que l’acquisition de forme d’onde
est arrêtée, le couplage d’entrée sur l’instrument est en réalité modifié lorsque la prochaine
acquisition de forme d’onde est exécutée. Faites attention à la tension d’entrée maximale.
• Pour toute information sur la manipulation de la sonde, se reporter au manuel d’utilisation
fourni avec la sonde.
Connecting Probes
Connect probes (or input cables such as BNC cables) to the input terminals on the bottom of the
front panel. The input impedance is 1 MΩ ± 1.0% and approximately 16 pF parallel or 50 Ω ± 1.0%.
Notes about Connections
• When connecting a probe to the instrument for the first time, perform phase correction of the
probe as described in section 2.5, “Correcting a Probe Phase.” If you don’t correct the probe
phase, the frequency characteristics will not be flat, and measurements will not be correct.
Perform phase correction on each channel to which a probe is to be connected.
• Please note that if the circuit being measured is directly connected to the instrument without the
use of a probe, correct measurements may not be possible because of the effect of the input
impedance of the instrument.
Note
Only use the standard accessory probes for this instrument. If you use other probes, the specifications of
this instrument may no longer be met.
